Extended Data Fig. 3: Absence of layer polarization under displacement field.
From: Optical control of orbital magnetism in magic-angle twisted bilayer graphene
Tight binding calculation showing the spin up and down bands at valley K of MATBG, for displacement fields of -0.3, 0 and 0.3 V/nm. Spin-orbit coupling from proximity to the WSe2 layer was included, resulting in spin-split bands. The colors represent the layer polarization of the corresponding wavefunctions. For displacement fields of ± 0.3 V/nm, the layer polarization is between ~ 0.45 and ~ 0.55 along the line cut. For no displacement field, layer polarization is between ~ 0.47 and ~ 0.53.
